WaterGuard™ PU is a 100% solids, two component, 1:1 mixing by volume, high performance, high build, fast set, aromatic and rigid polyurethane lining. It has been specifically designed as a corrosion and abrasion resistant coating for long term protection of water pipe internals. It complies with the requirements of NSF/ANSI 61 standard for potable water and AWWA C222 standard. It can also be used for other applications including raw water, process water, sewage, and wastewater. The product is made directly to surface prepared steel or ductile iron without a primer. Unlimited film build can be achieved in a single coat multi-pass application.

Excellent Performance Properties
WaterGuard™ PU cures to form a very hard and tough surface film with excellent resistance to abrasion, impact, chemical attack, and cathodic disbondment. It exhibits excellent adhesion on correctly prepared steel and ductile iron surfaces. Application of a primer is not necessary. The product is also compatible with most readily available field joint coating systems such as heat-shrinkable sleeves, liquid epoxy, FBE, and polyurethane coatings.

All Temperature Cure And Unlimited Film Build
WaterGuard™ PU can be cured at almost any ambient temperature. The product has a very fast curing time and is therefore applied using plural component spray equipment. Unlimited film build can be achieved in a single coat multi-pass application. The end result is a thick, impervious, and holiday free internal coating film within minutes of spray application. Inspection and quality testing can be made within 30 minutes and pipes can be put onto service within hours.

Environmentally Safe
The 100% solids, solvent and VOC free WaterGuard™ PU product is designed to meet strict Health, Safety and Environmental standards. The product contains only pure resins and the finished coating is safe for drinking water and food contact.
